(OP)
I am looking for help and guidance in the design of oily water sepeartors in a Tank farm. Can some one with experience let me know what to look for and references and API codes applicable in design and erection of oily water seperators.

Thank you

You can order them through www.api.org

RE: API - OILY WATER SEPERATORS

API.org is the correct address for general API information.
To order publications, API will send you to http://www.global.ihs.com/ where you can buy with a credit card and download a pdf of most API publications as well as other organizations' standards.

RE: API - OILY WATER SEPERATORS

First of all the oily water seperator shall be considered one equipment in the entire oily draiange system.However, depends on the operation modes( settlment of the crude/product in tank(s) or resident time before agitation) of  your tank farm, the  water disposed volum( BSW ) in the oil shall be caculated first through lab analysis. Then, you caculate the recovered oil in barrels. If the amount of the crude is appreciable( more than 0.2% by volume), the separator will be economicall and effecient specially if process big/large crude oil tanks. Otherwise, you go for good settlemnt and direct evapration or to a ground sump where you can repump it bcak to a pipeline or into one of the tanks in the tank farm. If you decide to go for a seperator( CPI or API( costly & require big space, yet it is good for high impurities oily water), approcah one of the vendors who have packaged oily sepeartors(CPI, requir less space and less costly, yet good for clean flow such as finished products in bulk plants) with a sump built in it, so you can pump the back wherever you decide. You may start with API-Pb-421 standard.
